blockchain is a technology which is achieved through the Bitcoin and it has been reduced by satoshi to this world so I believe no one will regret that at the same time Bitcoin will be always live in the crypto market.
So every uses in the crypto community never allow Bitcoin to lose it's name.
of course, Bitcoin is the life of Blockhcain, if Bitcoin doesn't exist then what does Blockchain mean? This technology is popular because of Bitcoin, and Bitcoin is famous for Blockchain.
